fix: VPC image scraping and show species name on plant edit

- vpc.py: target .wp-caption img for hero image (VPC uses Elementor, not
  standard WooCommerce gallery); skip logo and placeholder images by URL pattern
- plant_edit view: pass plant.species as 'species' so the species info
  banner (including scientific name) appears on the edit form
